l QM ATTORNEY l, i "i LOCK.

Application filed April 2,

To all whom it may concern: P

Be it known that 1, JOHN J. BONER, a citizen of the United States, residing at Blue Island, in the county of Cookand State of Illinois, have invented new and useful Improvements in Locks, of which the following is a specification.

This invention relates to locks and more particularly to a lock designed for use on freight cars to prevent theft of the merchandise therefrom.

An object of the invention isto provide a key operated locking structure which will co-operate with the sliding bolt used on freightor refrigerator cars in such a manner as to prevent the opening of the door even in case the seal is broken and further to pro vide a lock structure which will permit cars to be locked without sealing but if sealed in the usual manner the bolt-must be locked.

Another object of'this invention is to provide a lock structure as specified which comprises a movable bolt ada )ted for insertion through the ordinary I b0 t of a car door which look bolt is moved out of locking position by rotation of a disc, the said disc normally being held in locked position by a suitable latch releasable by a key.

Other objects of the invention will appear in the following retailed description and in the accompanying drawings where- Fig. 1 is a fragmentary side elevation of a freight car showing the lock applied and having a part broken away to expose the lock construction in locked position.

Fig. 2 is a detail side elevation of the lock, partly in section. showing it in an unlocked position.

Fig. 3 is a section through the lock taken on the line 3-3 of Fig. 2 showing the key inserted.

Fig. 4 is a detailed view of the key.

Fig. 5 is a detail side elevation illustrating the manner in which the ordinary bolt covers the key hole of the improved lock.

Fig. 6 is a view similar to Fig. 5 showing the parts in another position with a portion broken away. Referring more particularly to the drawing the improved lock structure is preferably carried by the door frame of a freight or refrigerator car, for which the lock is par ticularly adapted, however, it is to be understood that the lock may be used in connection with any type of opening closure mem- 1921.

ber desired without departing from the spirit of this invention.

The improved lock comprises a guide 1 which is provided with a longitudinally extending bolt. receiving slot 2 adapted to slidably receive therein. the ordinary locking bolt 3 such as used in connection with the locking pins and seals in freight cars at the present time. The locking bolt 3 is provided with a transversely extending opening 4 which is adapted to receive therethrough the locking bolt 5 of the lock'structure when thelatter is in lockingposition as shown'in Fig. 1 of the drawing. The bolt 5 extends transversely to the bolt 3 and it is provided with rack teeth '6 formed part way along one edge thereof. The rack teeth. 6- are provided for co-operation with the gear teeth 7 formed upon the perimeter of the disc 8 ofthe lock structure. The disc 8 is rotatably supported and has a rectangular axial .spindie 9 formed on its outer face as wellas being provided with a pair of rectangular openings 10 disposed, preferably, at angle to each other and having their innermost portions connected byan arcuate slot.

11. The rectangularopenings 10 are provided for receiving the latch bolt 12 which extends transversely to the disc 8 and is urged by a spring 13 into one of the rec tangular openings 10 outwardly of thearcuate slot 11 for locking the disc 8 against ro- A slidable arm 14 carries the latch tation. 12 and is urged downwardly by the spring 21. The arm l projects downwardly and has its lower end 15 positioned in the path of a cleat 16 on the bolt 3 so that when the bolt 3 is inserted. in the guide 2 the cleat 16 will engage the arm 14 and movethis arm upwardly, forcing the latch 12 into alignment with the arcuate slot 11.

In looking, when the bolt 3 is moved into place the cleat 16 will move the arm 14 thus moving the latch bolt 12 into registration with the arcuate slot 11 and the weight of the bolt 5 will cause it to drop into locking position, since the disc 8 is mounted for free rotation when the latch bolt 12 is in or movbolt 22 passes directly over the keyhole 25 of the lock structure preventing the insertion of a key into the lock until the seal is broken thereby providing double insurance against malicious tampering with the contents of a car equipped with the improved lock.

l/Vhen unlocking the improved lock; the key 17 is inserted through the key plate 18 with the recesses 19 in the key receiving the spindle 9 and with the arm 20 of the key bit extending through the opening 10 in. Which the latch bolt is engaged. The inserting of the key in place as above stated will move the latch bolt out of the recesses 10 permitting the disc 8 to be rotated and raise the bolt 5 out "of the opening i and release the bolt 3 for unlocking movement.

It is, of course, to be understood that the invention may be constructed in various other manners and the parts associated in difi'erent relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what 2 I claim is:

'1. In a lock, the combination with a looking bolt, of a second locking bolt extending transversely thereto and adapted for locking engagement with said first named locking bolt, rack teeth formed upon said said second locking bolt, a rotatable disc having gear teeth on its perimeter for co-acting with said rack teeth, and means-non mally restraining said disc against rotation.

2. In a lock, the combination with a locking bolt, of a second locking bolt extending transversely thereto and adapted for locking engagement with said first named locking bolt, rack teeth formed upon said second locking bolt, a rotatable disc having gear teeth on its perimeter for co-acting with said rack teeth, and means normally restraining said disc against rotation, a cleat upon said first named locking bolt for releasing said restraining means upon movement of the first named locking bolt into locking posi tion.

1 ,esaoea 3. In a lock, the combination of a locking bolt, a second locking bolt adapted to be moved into locking engagement with the first named locking bolt, rack teeth formed upon said second lock bolt, a rotatable disc, gear teeth upon the perimeter of said disc for engagement with said rack teeth to operate said second lock bolt by rotation of said disc, a latch bolt normally restraining said disc from rotation, and a key for re leasing said latch bolt and rotating said disc.

4. In a lock, the combination of a locking bolt, a second locking bolt adapted to be moved into locking engagement with the first named locking bolt, rack teeth formed upon said second look bolt, a rotatable disc, gear teeth upon the perimeter of said disc for engagement with said rack teeth to 0p erate said second look bolt by rotation of said disc, a latch bolt normallyrestraining said disc from rotation, a key for releasing said latch bolt and rotating said disc, and means operable by movement of said first named locking bolt into locking position to release said latch bolt to permit rotation of said disc.

5. In a lock, the combination of a locking bolt, a second locking bolt adapted to be moved into locking engagement with the first named locking bolt, rack teeth formed upon said second lock bolt, a rotatable disc, gear teeth upon the perimeter of said disc for engagement with said rack teeth to operate said second lock bolt by rotation of said disc, a latch bolt normally restraining said disc from rotation, a key for releasing said latch bolt and rotating said disc, an arm engaging said latch bolt, a. cleat carried by said first named locking bolt and adapted to engage said arm upon movement of the first named locking bolt into locking position for moving the latch bolt out of movement restraining position relative to said disc.

In testimony whereof I aflix my signature.

JOHN J. BONER.
